BESAPLAST Kunststoffe GmbH, Borken, produces waterstops for concrete construction — internal and external construction joint and expansion joint waterstops, capping joint tapes, joint sheets, moulded parts and formwork accessories.
Almost all products are manufactured at BESAPLAST's own factory and are therefore subject to a dedicated quality control regime. Patents, designs and trademarks underline the quality of the product range.
The DAT series was developed for tunnel construction: it provides pressure-watertight sealing towards the tunnel interior without affecting the reinforcement and with low formwork effort.
